In my area #10 Solid Aluminum was hooked around brass terminals, and worked for years, until jokers came along with pigtails that burned up.
I can't believe Owner-Builder permits, and GC laborer shops, are exclusive to California
Of course not, if you’re the one molesting existing construction
And I've done exactly that. A deep 4-11/16 with a raised mud ring at a receptacle or switch location for the #10 HR. #12 from there on out. That box is so big you could park your truck in it.
People can be a pain, with that said one way I found works best is talk money. That seems to motivate people more then anything else.
Good idea! The sub-panel would be about 60' away from the main panel (directly across the basement). It would handle the electric range (50A), electric dryer (30A), two SABC's (20A each), refrig (20A), dishwasher/disposal (20A), microwave (20A), and laundry (20A), for a total of 10 spaces. Would a 125A breaker on a 1/0 AL SER feeder work for this?
Take a look at this similar thread:
1/0 Al SER is rated for 120A @ 75 deg. You can’t use the 83% rule unless it’s feeding the entire structure.
I think if calculate it, you’ll find that #1AL on 100A will be adequate. Maybe even #2 on a 90.
ChatGPT told me #2 on 90A is undersized, and it suggested 1/0 and 125A. I didn't know they made #1 SER cable.
This subpanel will carry much of the load for the entire house. The only loads remaining are heating, AC and lights.
Don't trust ChatGPT for much. When I do a load calc, it comes to about 70A. So 90A feeder would be fine. Could do #4 copper on an 80A or 90A breaker, #3 copper on a 100A, #2 AL on a 90A.1/0 AL on a 125A would be overkill.
AI slop must be using 60 degrees. 95A @ 75.
Don't need the 83% rule. 120 amps is not a standard size so next size up rule would allow 125 amp over current protection.
